Fox ESS AI Link EMS Box for Three-Phase Multi-Inverter Systems
The Fox ESS AI Link (part number FE-AI-LINK) is a three-phase Energy Management System (EMS) controller designed to coordinate multiple Fox ESS inverters in parallel operation. It supports up to 10 inverters in on-grid mode and up to 4 H3-Pro inverters in off-grid mode, providing centralised control, export limitation, and system synchronisation via RS-485 communication. Compatible with the Fox ESS H3 Smart, H3-Pro, V-Series, and R-Series inverters, the AI Link can be powered directly from the H3-Pro, requiring no separate power supply. IP65 rated for indoor or outdoor wall-mounted installation, it measures 260 x 192 x 88 mm and weighs 2.5 kg. Available from DECO Group, a UK-based solar wholesaler for trade installers.

Common Questions
Click a question below to reveal the answer.
Which Fox ESS inverters are compatible with the AI Link?
The AI Link is compatible with Fox ESS H3 Smart, H3-Pro, V-Series, and R-Series three-phase inverters.
How many inverters can the Fox ESS AI Link control?
Up to 10 inverters in on-grid mode and up to 4 H3-Pro inverters in off-grid mode.
Do I still need individual monitoring dongles when using the AI Link?
No. The AI Link acts as a full system data logger for all connected inverters, so individual monitoring dongles are not required on each unit.
Does the Fox ESS AI Link need a separate power supply?
No. The AI Link can be powered directly from the H3-Pro inverter, eliminating the need for an external power supply.
When is the Fox ESS AI Link required?
The AI Link is required for parallel multi-inverter installations where standard daisy-chain RS-485 communication is insufficient. It provides centralised control, export limitation, and system synchronisation across all connected units.
